Embodiment 1

[0026] The preparation method of the above-mentioned foamed polyolefin antistatic material includes the following steps: (1) The foamed polyolefin base material is immersed in an antistatic liquid and water, the mass fraction is 1%, the pH is 7.0, and the temperature is In a solution at 20°C, make the solution absorb and cover the substrate, and the anti-static liquid is a commercially available anti-static liquid; (2) Preliminarily filter and dry until the substrate hangs without dripping; (3) ) A group of pressure rollers with a flexible surface are used to squeeze the preliminarily drained substrate covered with the anti-static liquid, and the squeezing force is 0.1N, so that the anti-static liquid is inside the substrate and The surface is evenly distributed; (4) Corona treatment on the surface of the substrate. The product is made.

Embodiment 2

[0028] A preparation method of a foamed polyolefin antistatic material, comprising the following steps: (1) immersing a foamed polyolefin substrate in an antistatic liquid and water, the mass fraction is 2%, the pH is 7.5, and the temperature is 25 In the solution at ℃, the solution is absorbed and covered on the substrate, and the anti-static liquid is a commercially available anti-static liquid; (3) A set of pressure rollers with a flexible surface are used to absorb and cover the initially filtered dry The base material of the anti-static liquid is extruded, and the pressing force is 3N, so that the anti-static liquid is uniformly distributed inside and on the surface of the base material; (4) corona treatment on the surface of the base material. The product is made.

Embodiment 3

[0030] The preparation method of the above-mentioned foamed polyolefin antistatic material includes the following steps: (1) The foamed polyolefin base material is immersed in an antistatic liquid and water. The mass fraction is 3%, the pH is 7.3, and the temperature is In a solution at 23°C, the solution is allowed to absorb and coat the substrate, and the anti-static liquid is a commercially available anti-static liquid; (2) Preliminarily filter to dry until the substrate hangs and does not drip; (3) ) A set of pressure rollers with a flexible surface are used to squeeze the preliminarily drained substrate covered with the anti-static liquid. The squeezing force is 5N, so that the anti-static liquid is inside and on the surface of the substrate. Uniform distribution; (4) Corona treatment on the surface of the substrate. The product is made.

Abstract

The invention relates to the field of high polymer materials and in particular relates to a foaming polyolefin anti-static material and a preparation method thereof. The material has the surface resistance of 10 <7-10> ohm, and comprises a foaming polyolefin base material and also comprises an anti-static fluid which exerts an anti-static effect and is sucked to the foaming polyolefin base material; an anti-static layer is formed by the anti-static fluid on the surface of the base material; the thickness of the anti-static layer is 0.1-1 micrometer. The preparation method comprises the following steps: (1) soaking the foaming polyolefin base material in a 1-5 mass percent of solution formed by adding water into the anti-static fluid, so that the solution is sucked to the base material; (2) performing primary draining; (3) allowing the anti-static fluid to be uniformly distributed inside and on the surface of the base material; (4) performing corona treatment on the surface of the base material. The obtained foaming polyolefin anti-static material is good and stable in physical performance and obvious in anti-static effect. The method for preparing the material is easy to operate and can be used for industrial production, the cost is reduced, and the environment is protected.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a foamed polyolefin antistatic material and a preparation method thereof. Background technique [0002] Foamed polyolefin material is a new type of material. It uses polyethylene, polypropylene or ethylene as the basic component and contains a large number of bubbles. Therefore, the foamed polyolefin material can also be said to be a composite material filled with gas. There are many varieties, but because they all contain a lot of bubbles, they have common characteristics, such as light weight, material saving, low thermal conductivity, good heat insulation performance, impact load absorption, excellent cushioning performance, good sound insulation performance, and specific strength High and good performance. However, the antistatic properties of this kind of foaming materials are relatively poor, so that it has defects in applications such as chemical pipelines and containers. It i...
